The line graph shows the amount of money Valen spent from January to June.
- Of the amount Valen spent in May, $131 was spent on food and the remaining amount was spent on clothes. How much did he spend on clothes in May?
- In which month did Valen spend $240 less than the previous month? Give your answer in this format. (Eg Jan)

Amount that Valen spent in May = $200
Amount that Valen spent on clothes

(b)
To find a decrease in a line graph, look for a decreasing slope.
The 2 decreasing slopes are from March to April and April to May. Now, find the month when Valen spent $240 less than the previous month.
Amount that Valen spent in March = $640
Amount that Valen spent in April = $400
Amount that Valen spent in April less than March
= 640 - 400
=
$240 (✓)
Amount that Valen spent in April = $400
Amount that Valen spent in May = $200
Amount that Valen spent in May less than April
= 400 - 200
= $200 (x)
The month that Valen spent $240 more than the previous month = Apr
Answer(s): (a) $69; (b) Apr
